This is the plot of one of the stories in I, Robot.
AI oracles are the central economic planners. But after years of perfection they have made a couple unusual "mistakes" and a human is trying to discover why.
How is that any different than what we already have? Just because the central planning is more covert, doesn't mean it's not happening. And we get all the expected "benefits" from it too, like repeated economic crises, and only the the powerful reaping the benefits.
